Description
Technical Field
[0001] The present invention relates to the technical field of hydraulic engineering pouring, and particularly relates to a pouring method for precast assembled components of a hydraulic concrete precast berthing lock pier. Background Art
[0002] Prefabricated buildings are the future direction of building development. At present, the application of precast components in industrial and civil buildings and transportation bridge projects is booming. Due to the particularity of the structure of hydraulic structures, the degree of application of precast components is very low. Traditional components of hydraulic buildings mostly adopt cast-in-place concrete structures, which require a large amount of formwork materials during construction, and also require steel bar laying and concrete construction on site, which is time-consuming and laborious, greatly affected by the environment, and has a high construction cost. At the same time, many connections of precast assembled components of hydraulic concrete adopt methods such as steel bar connection, and then concrete is cast in situ at the construction site, which seriously affects the construction period, has a large workload, complex construction, and is prone to quality problems, and is not conducive to ensuring the overall safety and quality of building precast components.
[0003] Chinese Patent Publication No. CN111827239A discloses a construction method for a precast berthing pier. Based on the traditional construction method of the berthing pier, through the setting of multiple sections of components, the precast structure of the pier body is composed of multiple sections, reducing the on-site construction workload, realizing the synchronous progress of foundation and component prefabrication. Through the setting of steel pipe anchor columns, the connection after component installation uses internal steel pipe anchor columns to connect each component in series, increasing the shear resistance at the splicing part, and meeting the mooring force and impact force of the berthing pier. It can be seen that the heat pipe performance detection device has the following problems: due to the offset during the installation process of the precast component and the pier platform, the connection is unstable, resulting in a decrease in the connection accuracy of the overall precast component. Summary of the Invention
[0004] Therefore, the present invention provides a pouring method for precast assembled components of a hydraulic concrete precast berthing lock pier to overcome the problem in the prior art that the connection is unstable due to the offset during the installation process of the precast component and the pier platform, resulting in a decrease in the connection accuracy of the overall precast component.
[0005] To achieve the above object, the present invention provides a pouring process for precast assembled components of a hydraulic concrete precast berthing lock pier, including:
[0006] Step S1, prefabricate the berthing lock pier, and reserve a post-cast strip on the precast pier platform. A number of steel bars of the same length are evenly arranged along the vertical direction on the inner circular arc of the post-cast strip;
[0007] Step S2, install the precast pier platform to the preset installation position, hoist the precast berthing lock pier to the installation position in the vertical direction through a hoisting device, and install the precast berthing lock pier vertically downward to the position of the post-cast strip;
[0008] In step S3, the central control module controls the visual detector installed on the hoisting equipment to detect the inclination angle of the ship-relying lock pier, and adjusts the concrete pouring density of the pouring channel in the first settlement area of the precast pier during the subsequent pouring process to the corresponding density according to the inclination angle, and adjusts the motor speed of the hoisting equipment during the vertical hoisting process to the corresponding speed according to the dislocation length of the precast lock pier on the upper surface of the precast pier detected by the visual sensor installed on the hoisting equipment;
[0009] Wherein, the first settlement area is a quarter equal-area rectangular area where the minimum settlement depth is located on the horizontal plane of the precast pier;
[0010] In step S4, use a concrete pouring device to pour the post-cast strip. After the pouring is completed, use a settlement monitoring sensor to periodically detect the settlement depth of the precast pier. The central control module adjusts the horizontal height of the precast pier during the subsequent installation process to the corresponding height according to the detected settlement depth.
[0011] Furthermore, a circular pouring channel is reserved on one side of the precast pier connected to the post-cast strip in the horizontal direction, and a number of reserved steel bar holes equal to the number of the steel bars are arranged at the bottom of the precast ship-relying lock pier.
[0012] Furthermore, in step S2, the installation process of installing the precast ship-relying lock pier at the position of the post-cast strip includes:

[0014] In step S22, use the hoisting equipment to move the precast ship-relying lock pier above the reserved steel bars of the precast pier and then stand still again until it is in a static state;
[0015] In step S23, corresponding marks are set on the reserved steel bar holes and the reserved steel bars. By using a detector to align the corresponding marks, the reserved steel bar holes under the precast ship-relying lock pier assembly are vertically aligned with the reserved steel bars below, and the precast ship-relying lock pier assembly is moved downward until the reserved steel bars completely enter the reserved steel bar holes.
[0016] Furthermore, in step S3, the central control module determines three types of determination methods for whether the connection stability between the precast ship-relying lock pier and the precast pier is within the allowable range according to the inclination angle of the ship-relying lock pier, wherein,
[0017] The first type of stability determination method is that the central control module determines that the connection stability between the precast ship-relying lock pier and the precast pier is within the allowable range under the preset first angle condition;

[0019] The third type of stability determination method is that the central control module determines that the connection stability between the precast ship-retaining lock pier and the precast pier platform is lower than the allowable range under the preset third angle condition, and adjusts the pouring density of the concrete in the pouring channel of the first settlement area on the precast pier platform during the subsequent pouring process to the corresponding density according to the difference between the inclination angle of the ship-retaining lock pier and the preset second inclination angle;
[0020] Wherein, the preset first angle condition is that the inclination angle of the ship-retaining lock pier is less than or equal to the first preset inclination angle, the preset second angle condition is that the inclination angle of the ship-retaining lock pier is greater than the first preset inclination angle and less than or equal to the second preset inclination angle, and the preset third angle condition is that the inclination angle of the ship-retaining lock pier is greater than the second preset inclination angle, the first preset inclination angle and less than the second preset inclination angle.
[0021] Further, the central control module determines three types of adjustment methods for the pouring density of the concrete in the pouring channel for the first settlement area according to the difference between the inclination angle of the ship-retaining lock pier and the second preset inclination angle under the preset third angle condition, wherein,
[0022] The first type of settlement adjustment method is that the central control module adjusts the subsequent concrete pouring density to the corresponding density under the preset first settlement inclination difference condition,
[0023] The second type of settlement adjustment method is that the central control module adjusts the subsequent concrete pouring density to the first preset density using the preset first density adjustment coefficient under the preset second settlement inclination difference condition,
[0024] The third type of settlement adjustment method is that the central control module adjusts the subsequent concrete pouring density to the second preset density using the preset second density adjustment coefficient under the preset third settlement inclination difference condition,
[0025] Among them, the preset first settlement inclination difference condition is that the difference between the inclination angle of the ship lock pier and the second preset inclination angle is less than or equal to the first preset settlement inclination difference; the preset second settlement inclination difference condition is that the difference between the inclination angle of the ship lock pier and the second preset inclination angle is greater than the first preset settlement inclination difference and less than or equal to the second preset settlement inclination difference; the preset third settlement inclination difference condition is that the difference between the inclination angle of the ship lock pier and the second preset inclination angle is greater than the second preset settlement inclination difference and less than the second preset settlement inclination difference, and the preset first density adjustment coefficient is less than the preset second density adjustment coefficient.
[0026] Further, the central control module has two types of secondary determination methods for determining whether the connection stability between the prefabricated ship lock pier and the prefabricated pier platform is within the allowable range according to the dislocation length of the prefabricated pier on the upper surface of the prefabricated pier under the preset second angle condition. Among them,
[0027] The first type of stability secondary determination method is that the central control module determines that the connection stability between the prefabricated ship lock pier and the prefabricated pier platform is within the allowable range under the preset first dislocation length condition.
[0028] The second type of stability secondary determination method is that the central control module determines that the connection stability between the prefabricated ship lock pier and the prefabricated pier platform is lower than the allowable range under the preset second dislocation length condition, and adjusts the motor speed during the subsequent vertical hoisting process to the corresponding speed by calculating the difference between the dislocation length on the upper surface of the prefabricated pier and the first preset dislocation length.
[0029] Among them, the preset first dislocation length condition is that the dislocation length of the prefabricated pier on the upper surface of the prefabricated pier platform is less than or equal to the first preset dislocation length, and the preset second dislocation length condition is that the dislocation length of the prefabricated pier on the upper surface of the prefabricated pier platform is greater than the first preset dislocation length.
[0030] Further, the central control module determines two types of adjustment methods for the motor speed during the subsequent vertical hoisting process according to the difference between the dislocation length on the upper surface of the prefabricated pier and the first preset dislocation length. Among them,
[0031] The first type of speed adjustment method is that the central control module adjusts the motor speed to the preset speed under the preset first dislocation length difference condition.
[0032] The second type of speed adjustment method is that the central control module uses the preset speed adjustment coefficient to lower the motor speed to the corresponding speed under the preset second dislocation length difference condition.
[0033] Wherein, the preset first misalignment length difference condition is that the difference between the misalignment length of the precast gate pier on the upper surface of the precast pier and the first preset misalignment length is less than or equal to the first preset misalignment length difference, and the preset second misalignment length difference condition is that the difference between the misalignment length of the precast gate pier on the upper surface of the precast pier and the first preset misalignment length is greater than the first preset misalignment length difference, and the preset rotational speed adjustment coefficient is less than 1.
[0034] Further, in the step S4, the central control module determines whether the settlement depth is within the allowable range in two types of determination methods based on the measured settlement values periodically measured by the settlement monitoring sensor, wherein,
[0035] The first type of settlement determination is that the central control module determines that the settlement depth is within the allowable range under the preset first settlement distance condition.
[0036] The second type of settlement determination is that the central control module determines that the settlement depth is lower than the allowable range under the preset second settlement distance condition. The central control module adjusts the height of the subsequent precast pier to the corresponding height by using the preset settlement adjustment coefficient based on the difference between the measured settlement depth and the preset settlement depth. Wherein, the preset first settlement distance condition is that the measured settlement depth is less than or equal to the preset settlement depth, and the preset second settlement distance condition is that the measured settlement depth is greater than the preset settlement depth.
[0037] Further, the central control module determines two types of adjustment methods for the height of the subsequent precast pier according to the difference between the measured settlement distance and the preset settlement distance under the preset second settlement distance condition, wherein,
[0038] The first type of height adjustment method is that under the preset first settlement distance difference condition, the central control module adjusts the height of the subsequent precast pier to the corresponding height and continues to manufacture the subsequent precast piers.
[0039] The second type of height adjustment method is that under the preset second settlement distance difference condition, the central control module adjusts the height of the subsequent precast pier to the first preset height by using the preset first settlement adjustment coefficient.
[0040] The third type of height adjustment method is that under the preset third settlement distance difference condition, the central control module adjusts the height of the subsequent precast pier to the second preset height by using the preset second settlement adjustment coefficient.
[0041] Among them, the preset first settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is less than or equal to the first preset settlement difference; the preset second settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is greater than the first preset settlement difference and less than or equal to the second preset settlement difference; the preset third settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is greater than the second preset settlement difference; the first preset settlement difference is less than the second preset settlement difference; the preset first settlement adjustment coefficient is less than the preset second settlement adjustment coefficient.
[0042] Further, when installing subsequent precast pier and abutment, a settlement prediction function is fitted based on the periodically measured settlement depth. The subsequent construction period is input into the settlement prediction function to calculate the predicted settlement distance, and the horizontal installation height of the subsequent precast pier and abutment is adjusted by a depth equal to the predicted settlement distance according to the predicted settlement distance.
[0043] Compared with the prior art, the beneficial effect of the present invention lies in the casting method of components, including precast pier and abutment, which reserves a post-cast strip, has a casting channel between the post-cast strip and the outside, and has several steel bars of the same length; the precast component of the pier near the lock is reserved with several steel bar holes. The central control module adjusts the concrete casting density and the motor speed during the subsequent vertical lifting process according to the difference between the inclination angle of the pier near the lock and the preset inclination angle, and adjusts the height of the subsequent precast pier and abutment according to the settlement depth after casting. The present invention improves the accuracy of casting the precast component of the pier near the lock made of hydraulic concrete.
[0044] Further, in the casting method of the present invention, a circular casting channel connecting the post-cast strip and the outside of the precast pier and abutment is arranged inside the precast component. Several reserved steel bar holes with the same number and corresponding positions as the steel bars are arranged at the bottom of the precast pier near the lock, making the installation of the precast pier near the lock and the precast pier and abutment more accurate and improving the accuracy of the casting process.
[0045] Further, the casting method of the present invention sets a preset first angle condition, a preset second angle condition, and a preset third angle condition. If the difference between the measured inclination angle of the pier near the lock and the horizontal direction is greater than the preset value, it indicates that the connection stability between the precast pier near the lock and the precast pier and abutment is lower than the allowable range, which will cause the precast component to tilt after casting, thus improving the accuracy of the casting process.
[0046] Further, the pouring method of the present invention is provided with a first settlement inclination difference condition, a second settlement inclination difference condition, a third settlement inclination difference condition, a preset first density adjustment coefficient, and a preset second density adjustment coefficient. The central control module adjusts the concrete pouring density using the corresponding adjustment coefficient according to the difference between the inclination angle of the pier near the ship lock and the second preset inclination angle, and reduces the impact caused by uneven settlement by adjusting the concrete pouring density, thereby improving the accuracy of the pouring process.
[0047] Further, the pouring method of the present invention is provided with a preset first misalignment length condition and a preset second misalignment length condition. When the misalignment length of the precast pier on the upper surface of the precast pier platform is greater than the preset misalignment length, it indicates that the motor speed exceeds the allowable range during the vertical lifting process, which will cause subsequent horizontal deviation during the vertical lifting process, thereby improving the accuracy of the installation process.
[0048] Further, the pouring method of the present invention is provided with a preset first misalignment length difference condition, a preset second misalignment length difference condition, and a preset rotation speed adjustment coefficient. The central control module adjusts the motor speed according to the difference between the misalignment length of the upper surface of the precast pier platform and the first preset misalignment length, and reduces the impact of tremors during transportation by adjusting the motor speed, thereby improving the accuracy of the installation process.
[0049] Further, the pouring method of the present invention is provided with a preset first settlement distance condition and a preset second settlement distance condition. A large difference between the settlement distance of the precast pier platform after pouring and the preset settlement distance indicates a large settlement degree, which will cause a large horizontal height difference or cracking of the pier platform after subsequent pouring. The central control module determines the settlement degree, thereby improving the accuracy of subsequent installation.
[0050] Further, the pouring method of the present invention is provided with a first settlement distance difference condition, a second settlement distance difference condition, a third settlement distance difference condition, a preset first settlement adjustment coefficient, and a preset first settlement adjustment coefficient. The central control module uses the difference between the measured settlement distance and the preset settlement distance to adjust the height of the subsequent precast pier platform, thereby improving the accuracy of subsequent installation.

A casting method of a hydraulic concrete prefabricated ship lock pier assembly component of the present invention comprises:
[0061] Step S1, prefabricate the pier adjacent to the ship lock, and reserve a post-cast strip on the prefabricated pier platform. A number of steel bars of the same length are evenly arranged along the vertical direction on the inner circular arc of the post-cast strip;
[0062] Step S2, install the prefabricated pier platform to the preset installation position. Use a hoisting device to hoist the prefabricated pier adjacent to the ship lock to the installation position in the vertical direction, and install the prefabricated pier adjacent to the ship lock vertically downward to the position of the post-cast strip;
[0063] Step S3, the central control module controls the visual detector set on the hoisting device to detect the inclination angle of the pier adjacent to the ship lock, and adjusts the concrete pouring density of the pouring channel in the first settlement area on the prefabricated pier platform during the subsequent pouring process to the corresponding density according to the inclination angle, and adjusts the motor speed of the hoisting device during the vertical hoisting process to the corresponding speed according to the dislocation length of the prefabricated lock pier detected by the visual sensor set on the hoisting device;
[0064] Wherein, the first settlement area is a quarter equal-area rectangular area where the minimum settlement depth is located on the horizontal plane of the prefabricated pier platform;
[0065] Step S4, use a concrete pouring device to pour the post-cast strip. After the pouring is completed, use a settlement monitoring sensor to periodically detect the settlement depth of the prefabricated pier platform. The central control module adjusts the horizontal height of the prefabricated pier platform during the subsequent installation process to the corresponding height according to the detected settlement depth.
[0066] The beneficial effect of the present invention lies in the pouring method of the component, including a prefabricated pier platform which reserves a post-cast strip, there is a pouring channel between the post-cast strip and the outside, and a number of steel bars of the same length are reserved; a prefabricated pier adjacent to the ship lock assembled component which reserves a number of steel bar holes. The central control module adjusts the concrete pouring density and the motor speed during the subsequent vertical hoisting process according to the difference between the inclination angle of the pier adjacent to the ship lock and the preset inclination angle, and adjusts the height of the subsequent prefabricated pier platform according to the settlement depth after pouring. The present invention improves the accuracy of the pouring of the prefabricated pier adjacent to the ship lock assembled component of hydraulic concrete.
[0067] Please continue to refer to Figure 1 As shown, a circular pouring channel is reserved on one side of the prefabricated pier platform connected to the post-cast strip in the horizontal direction, and a number of reserved steel bar holes equal to the number of the steel bars are arranged at the bottom of the prefabricated pier adjacent to the ship lock.
[0068] Please continue to participate in Figure 3 As shown, in the step S2, the installation process of installing the prefabricated pier adjacent to the ship lock to the position of the post-cast strip includes:
[0069] Step S21: Use the hoisting device to lift the precast lock abutment to be installed above the height of the reserved steel bars on the precast pier platform.
[0070] Step S22: Use the hoisting device to move the precast lock abutment above the reserved steel bars of the precast pier platform and then statically wait until it reaches a stationary state again.
[0071] Step S23: The reserved steel bar holes and the reserved steel bars are provided with corresponding marks. By using a detector to align the corresponding marks, vertically align the reserved steel bar holes under the precast lock abutment assembled component with the reserved steel bars below, and move the precast lock abutment assembled component downward until the reserved steel bars completely enter the reserved steel bar holes.
[0072] Furthermore, in the casting method of the present invention, the precast component is arranged inside the precast pier platform to connect the post-cast strip with the circular casting channel on the outer side of the precast pier platform. A number of reserved steel bar holes with the same number and corresponding positions as the steel bars are provided at the bottom of the precast lock abutment, making the installation of the precast lock abutment and the precast pier platform more accurate and improving the accuracy of the casting process.
[0073] Please continue to participate Figure 4 As shown, in step S3, the central control module determines whether the connection stability between the precast lock abutment and the precast pier platform is within the allowable range according to the inclination angle of the lock abutment in three types of determination methods. Among them,
[0074] The first type of stability determination method is that the central control module determines that the connection stability between the precast lock abutment and the precast pier platform is within the allowable range under the preset first angle condition.
[0075] The second type of stability determination method is that the central control module determines that the connection stability between the precast lock abutment and the precast pier platform is lower than the allowable range under the preset second angle condition, initially determines that the hoisting stability is lower than the allowable range, and makes a secondary determination on whether the hoisting stability is lower than the allowable range according to the misalignment length of the precast pier on the upper surface of the precast pier platform.
[0076] The third type of stability determination method is that the central control module determines that the connection stability between the precast lock abutment and the precast pier platform is lower than the allowable range under the preset third angle condition, and adjusts the concrete pouring density of the pouring channel in the first settlement area on the precast pier platform during the subsequent pouring process to the corresponding density according to the difference between the inclination angle of the lock abutment and the preset second inclination angle.
[0077] Among them, the preset first angle condition is that the inclination angle of the pier adjacent to the lock is less than or equal to the first preset inclination angle, the preset second angle condition is that the inclination angle of the pier adjacent to the lock is greater than the first preset inclination angle and less than or equal to the second preset inclination angle, and the preset third angle condition is that the inclination angle of the pier adjacent to the lock is greater than the second preset inclination angle, the first preset inclination angle and less than the second preset inclination angle;
[0078] Specifically, the preset inclination angle of the pier adjacent to the lock is θ, the first preset inclination angle is θ1, and the second preset inclination angle is θ2.
[0079] The pouring method of the present invention is provided with a preset first angle condition, a preset second angle condition, and a preset third angle condition. Measuring that the angle difference between the inclination angle of the pier adjacent to the lock and the horizontal direction is greater than the preset value indicates that the connection stability between the precast pier adjacent to the lock and the precast pier platform is lower than the allowable range, which will cause the precast components to tilt after pouring, achieving an improvement in the accuracy of the pouring process.
[0080] Please continue to refer to Figure 4 As shown, under the preset third angle condition, the central control module determines three types of adjustment methods for the concrete pouring density of the pouring channel for the first settlement area according to the difference between the inclination angle of the pier adjacent to the lock and the second preset inclination angle. Among them,
[0081] The first type of settlement adjustment method is that under the preset first settlement inclination difference condition, the central control module adjusts the subsequent concrete pouring density to the corresponding density.
[0082] The second type of settlement adjustment method is that under the preset second settlement inclination difference condition, the central control module uses the preset first density adjustment coefficient to adjust the subsequent concrete pouring density to the first preset density.
[0083] The third type of settlement adjustment method is that under the preset third settlement inclination difference condition, the central control module uses the preset second density adjustment coefficient to adjust the subsequent concrete pouring density to the second preset density.
[0084] Among them, the preset first settlement inclination difference condition is that the difference between the inclination angle of the pier adjacent to the lock and the second preset inclination angle is less than or equal to the first preset settlement inclination difference, the preset second settlement inclination difference condition is that the difference between the inclination angle of the pier adjacent to the lock and the second preset inclination angle is greater than the first preset settlement inclination difference and less than or equal to the second preset settlement inclination difference, the preset third settlement inclination difference condition is that the difference between the inclination angle of the pier adjacent to the lock and the second preset inclination angle is greater than the second preset settlement inclination difference, the first preset settlement inclination difference and less than the second preset settlement inclination difference, and the preset first density adjustment coefficient is less than the preset second density adjustment coefficient;
[0085] Specifically, the difference between the preset inclination angle of the berthing lock pier and the second preset inclination angle is Δθ, the first preset settlement inclination difference is Δθ1, the second preset settlement inclination difference is Δθ2, the preset first density adjustment coefficient is ɑ1, the preset second density adjustment coefficient is ɑ2, where Δθ1 < Δθ2 and ɑ1 < ɑ2. The preset density is denoted as ρ0, and the adjusted concrete pouring density is ρ’ = ρ0×(1 + αi) / 2, where αi is the preset i-th density adjustment coefficient, and i = 1, 2 is set.
[0086] The pouring method of the present invention is provided with a first settlement inclination difference condition, a second settlement inclination difference condition, a third settlement inclination difference condition, a preset first density adjustment coefficient, and a preset second density adjustment coefficient. The central control module adjusts the concrete pouring density using the corresponding adjustment coefficient according to the difference between the inclination angle of the berthing lock pier and the second preset inclination angle, and reduces the influence caused by uneven settlement by adjusting the concrete pouring density, thereby improving the accuracy of the pouring process.
[0087] Please continue to refer to Figure 4 As shown, the central control module has two types of secondary determination methods for determining whether the connection stability between the precast berthing lock pier and the precast pier platform is within the allowable range according to the misalignment length of the precast lock pier on the upper surface of the precast pier under the preset second angle condition, where
[0088] The first type of stability secondary determination method is that the central control module determines that the connection stability between the precast berthing lock pier and the precast pier platform is within the allowable range under the preset first misalignment length condition.
[0089] The second type of stability secondary determination method is that the central control module determines that the connection stability between the precast berthing lock pier and the precast pier platform is lower than the allowable range under the preset second misalignment length condition, and adjusts the motor speed during the subsequent vertical lifting process to the corresponding speed by calculating the difference between the misalignment length on the upper surface of the precast pier and the first preset misalignment length.
[0090] Among them, the preset first misalignment length condition is that the misalignment length of the precast lock pier on the upper surface of the precast pier is less than or equal to the first preset misalignment length, and the preset second misalignment length condition is that the misalignment length of the precast lock pier on the upper surface of the precast pier is greater than the first preset misalignment length;
[0091] Specifically, the preset misalignment length of the precast lock pier on the upper surface of the precast pier is L, the first preset misalignment length is L1, and the preset speed adjustment coefficient is β < 1.
[0092] The pouring method described in the present invention is provided with a preset first misalignment length condition and a preset second misalignment length condition. When the misalignment length of the precast pier on the upper surface of the precast pier platform is greater than the preset misalignment length, it indicates that the motor speed exceeds the allowable range during the vertical lifting process, which will cause subsequent horizontal offsets to continue to occur during the vertical lifting process, achieving an improvement in the accuracy of the installation process.
[0093] Please continue to refer to Figure 4 As shown, the central control module determines two types of adjustment methods for the motor speed during the subsequent vertical lifting process according to the difference between the misalignment length on the upper surface of the precast pier platform and the first preset misalignment length. Among them,
[0094] The first type of speed adjustment method is that when the central control module is under the preset first misalignment length difference condition, the central control module adjusts the motor speed to the preset speed.
[0095] The second type of speed adjustment method is that when the central control module is under the preset second misalignment length difference condition, the central control module uses the preset speed adjustment coefficient to lower the motor speed to the corresponding speed.
[0096] Among them, the preset first misalignment length difference condition is that the difference between the misalignment length of the precast pier on the upper surface of the precast pier platform and the first preset misalignment length is less than or equal to the first preset misalignment length difference. The preset second misalignment length difference condition is that the difference between the misalignment length of the precast pier on the upper surface of the precast pier platform and the first preset misalignment length is greater than the first preset misalignment length difference, and the preset speed adjustment coefficient is less than 1.
[0097] Specifically, let the difference between the misalignment length of the precast pier on the upper surface of the precast pier platform and the first preset misalignment length be ∆L, and the first preset misalignment length difference be ∆L1.
[0098] The pouring method described in the present invention is provided with a preset first misalignment length difference condition, a preset second misalignment length difference condition and a preset speed adjustment coefficient. The central control module adjusts the motor speed according to the difference between the misalignment length on the upper surface of the precast pier platform and the first preset misalignment length, and reduces the influence of tremors during transportation by adjusting the motor speed, achieving an improvement in the accuracy of the installation process.
[0099] Please continue to refer to Figure 2 As shown, in step S4, the central control module determines whether the settlement depth is within the allowable range in two types of determination methods based on the measured settlement values periodically measured by the settlement monitoring sensor. Among them,
[0100] The first type of settlement determination is that when the central control module is under the preset first settlement distance condition, it determines that the settlement depth is within the allowable range.
[0101] The second type of settlement determination is that the central control module determines that the settlement depth is lower than the allowable range under the condition of a preset second settlement distance. The central control module adjusts the height of the subsequent precast pier to the corresponding height by using a preset settlement adjustment coefficient based on the difference between the measured settlement depth and the preset settlement depth. Among them, the preset first settlement distance condition is that the measured settlement depth is less than or equal to the preset settlement depth, and the preset second settlement distance condition is that the measured settlement depth is greater than the preset settlement depth;
[0102] Specifically, the preset measured settlement depth is H, and the preset settlement depth is H1.
[0103] Specifically, the pouring method of the present invention is provided with a preset first settlement distance condition and a preset second settlement distance condition. A large difference between the settlement distance of the precast pier after pouring and the preset settlement distance indicates a large settlement degree, which will cause a large horizontal height difference or cracking of the pier after subsequent pouring. The central control module determines the settlement degree, improving the accuracy of subsequent installation.
[0104] Please continue to refer to Figure 2 As shown, the central control module determines two types of adjustment methods for the height of the subsequent precast pier according to the difference between the measured settlement distance and the preset settlement distance under the condition of the preset second settlement distance. Among them,
[0105] The first type of height adjustment method is that the central control module adjusts the height of the subsequent precast pier to the corresponding height under the condition of the preset first settlement distance difference, and continues to manufacture the subsequent precast pier.
[0106] The second type of height adjustment method is that the central control module adjusts the height of the subsequent precast pier to the first preset height by using a preset first settlement adjustment coefficient under the condition of the preset second settlement distance difference.
[0107] The third type of height adjustment method is that the central control module adjusts the height of the subsequent precast pier to the second preset height by using a preset second settlement adjustment coefficient under the condition of the preset third settlement distance difference.
[0108] Among them, the preset first settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is less than or equal to the first preset settlement difference. The preset second settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is greater than the first preset settlement difference and less than or equal to the second preset settlement difference. The preset third settlement distance difference condition is that the difference between the measured settlement distance and the preset settlement distance is greater than the second preset settlement difference. The first preset settlement difference is less than the second preset settlement difference, and the preset first settlement adjustment coefficient is less than the preset second settlement adjustment coefficient;
[0109] Specifically, the difference between the preset measured settlement distance and the preset settlement distance is ∆H, the first preset settlement difference is ∆H1, the second preset settlement difference is ∆H2, the preset first settlement adjustment coefficient is β1, and the preset second settlement adjustment coefficient is β2. Among them, ∆H1 < ∆H2, 1 < β2, the preset corresponding settlement depth is H0, and the adjusted settlement depth is H'. It is set that H' = H0×(1 + βj), where βj is the preset j-th settlement adjustment coefficient, and j = 1, 2 is set.
[0110] The pouring method of the present invention is provided with a preset first settlement distance difference condition, a preset second settlement distance difference condition, a preset third settlement distance difference condition, a preset first settlement adjustment coefficient, and a preset second settlement adjustment coefficient. The central control module uses the difference between the measured settlement distance and the preset settlement distance to adjust the height of the subsequent precast pier, thereby improving the accuracy of subsequent installation.
[0111] When installing the subsequent precast pier, a settlement prediction function is fitted based on the periodically measured settlement depth. The subsequent construction period is input into the settlement prediction function to calculate the predicted settlement distance, and the horizontal installation height of the subsequent precast pier is adjusted by a depth equal to the predicted settlement distance according to the predicted settlement distance.

Among them, ∆θ1 = 3°, ∆θ = 7°, ρ0 = 3 kg / m 3 , ɑ1 = 2.0, ɑ2 = 2.5,
[0114] In this Embodiment 1, ∆θ = 5° is obtained. The central control module determines that ∆θ1 < ∆θ < ∆θ2 and uses ɑ1 to adjust the pouring density of the concrete. After adjustment, ρ' = 3 kg / m 3 ×(1 + 2.0) / 2 = 4.5 kg / m 3 .
[0115] The difference between the preset measured settlement distance and the preset settlement distance is ∆H, the first preset settlement difference is ∆H1, the second preset settlement difference is ∆H2, the preset first settlement adjustment coefficient is β1, and the preset second settlement adjustment coefficient is β2. Among them, ∆H1 = 0.2 m, ∆H2 = 0.4 m, β1 = 1.1, β2 = 1.2, H0 = 1 m,
[0116] In this Embodiment 1, ΔH = 0.25 m is obtained. The central control module determines that ΔH1 < ΔH < ΔH2, and uses β1 to adjust the settlement depth of the subsequent precast pier and abutment. After adjustment, H’ = 1 m × (1 + 1.1) / 2 = 1.05 m.
[0117] In this embodiment, by calculating the difference between the inclination angle of the pier near the ship lock and the preset inclination angle, the concrete pouring density and the motor speed during the subsequent vertical hoisting process are adjusted, and the height of the subsequent precast pier and abutment is adjusted according to the settlement depth after pouring, thus realizing the accuracy of the casting of the precast assembled component of the hydraulic concrete pier near the ship lock.
